When should I run the /impact command?

You should run it before refactoring core logic, changing shared types, deleting exports, or modifying API signatures to understand potential breaking changes.

How does this skill identify code dependents?

The skill uses Grep and Glob tools to search for imports, function calls, and type references across your entire repository to map the dependency chain.

Can I use it on uncommitted work?

Absolutely. If no specific file or function is provided as input, the skill will automatically analyze your current uncommitted changes.

Does it automatically check test coverage?

Yes, it identifies existing unit and integration tests related to the modified code and flags which tests may require updates due to your changes.

Developer Tools

Analyzes system-wide ripple effects of code changes to prevent regressions and breaking changes in shared components.

This skill empowers developers to perform proactive impact analysis before modifying shared utilities, refactoring core functionality, or changing API signatures. By searching for direct dependents, tracing downstream effects, and identifying relevant test coverage, it provides a comprehensive risk assessment that prevents surprise breakages in unrelated parts of the codebase. It transforms 'blind' changes into informed migrations, ensuring that every modification is accounted for across the entire system through detailed reports and actionable recommendations.

Key Features

01Automated dependency tracing for shared utilities and types

02Actionable coordination reports for synchronized file updates

03Assessment of unit and integration test coverage for planned changes
